Title: Improvements in or relating to the measurement of low pressures
Inventor: BECK ARNOLD HUGH WILLIAM
IPC: H01J41/04
Filed: 1952-07-29
Abstract: 771,800. Electric tests. STANDARD TELEPHONES & CABLES, Ltd. July 29, 1952, No. 37786/54. Divided out of 771,799, [Group XL (a)]. Addition to 678,695. Class 37. An arrangement for the measurement and/or detection of leaks in low pressure systems comprises a pair of ionization manometer tubes 30 and 31 of the type disclosed in the parent Specification or of the improved type disclosed in Specification 771,799 [Group XL (a)] each tube, in addition to the normal solenoid 41 connected to a D.C. supply 42, being provided with an additional solenoid 43 connected to an A.C. supply 44 so that when the flux along the axis of tube 30 is increasing, that along the axis of tube 31 is decreasing. The tubes are connected through a cold trap 33 and are inserted between the system under test, denoted by " leak," and vacuum pumps 32. The anodes 34 of the tubes are connected in common to a terminal 35 for connection to a 6 kv. supply and the guard electrodes 40 are connected to ground. The cathode 36 of tube 30 is connected through a variable load resistor 37 to ground and through a blocking capacitor 45 to the grid 47 of a double triode amplifier tube 49. The cathode 38 of tube 31 is connected through a fixed resistor 39 to ground and through a capacitor 46 to the grid 48 of the tube 49. The cathodes of this tube are connected in common to ground through a self-bias circuit 50 and the anodes 52 are connected in common through a tuned circuit 53, adjusted to the frequency of the source 44, to an H.T. supply terminal 55 and through a capacitor 57 to an amplifier 58 feeding a meter 59. If air is entering the system it will affect both tubes 30 and 31 similarly so that their outputs will be approximately the same, but because of the reversed polarity of the modulating windings 43 the voltages appearing on the grids of tube 49 will be in opposition and hence, when the circuit is balanced by adjustment of resistor 37 there will be no output to the amplifier 58. Butane, or other gas which will liquefy in the cold trap 33 is sprayed over the exterior of the system where the leaks are suspected. Butane entering tube 30 increases the output of the tube so that the voltage across resistor 37 is increased. The butane is liquefied in the cold trap 33 and so does not enter tube 31, the output of which is, if anything, reduced because the butane has replaced some of the air previously entering the system. An output therefore appears on meter 59 which may be calibrated in terms of known leaks through standard capillary tubes. In an alternative arrangement the load resistors 37 and 39 are connected between the anodes 34 and terminal 35 and the cathodes 36 and 38 are grounded, the guard electrodes 40 being connected directly to terminal 35.

Title: Improved means for dispensing measured quantities of beer and other liquid
IPC: B67D1/00
Filed: 1959-11-10
Abstract: 909,955. Delivering measured quantities of liquid. WALLACE, J. Feb. 8, 1961 [Nov. 10, 1959; April 4, 1960 ; Aug. 24, 1960], Nos. 38034/59, 11773/60 and 29219/60. Class 106 (5). A dispensing device, particularly for beer or other gas-charged liquids, has a chamber 2 divided into two compartments by a flexible diaphragm 4, manually-operated valve means for admitting the liquid on one or other side of the diaphragm and a receptacle 11 preceding the measuring compartments and serving to trap the free gases given off by the liquid so that the gases form a cushion for maintaining pressure on the liquid. The chamber 2 may be above or below the receptacle 11. In Fig. 1, the beer is admitted to the receptacle 11 through a pipe 20 and is directed to one or other side of the diaphragm 4 by a valve plate 10 which has two diametrically-opposite ports 8, 8a and is rotatable through 180 degrees by a knob 17. The beer discharged from one side of the diaphragm passes up a pipe 27 and duct 28 to a spring-loaded valve 32 which can be lifted from its seat 24 by the lip of a tumbler. The pressure of the beer acts on a diaphragm 35 on the valve and adjusts the position of a valve member 33 relative to a shoulder 31 so that the rate of flow is substantially constant irrespective of variations in the beer pressure. Grids 5b, 5c are provided at the ports of the measuring compartment to prevent the diaphragm from covering them before a compartment is fully discharged. A bleed-off tube 23a extends into the upper end of the receptacle 11 to a predetermined depth and communicates through a valve to the duct 28 ; for initial charging of the device, the bleedoff valve is opened until beer begins to flow from the outlet 24. In a modification, the outlet and bleed-off valves are mounted adjacent the knob 17 and are of the needle-valve type. In the modification shown in Fig. 5, a second valve plate 40 rotatable by a spring-loaded handle 48 is provided above the valve plate 10 and has a pair of passages 41, 42 corresponding to the valve ports 8, 8a and an arcuate groove which can be set so that a bleed-off tube 51 can be connected to the outlet 50 for initial charging of the receptacle. The rate of flow can be controlled by turning valve plate 40 to mask the foot of the delivery tube 27. The outlet 53, Fig. 11, may be provided with a shutter 54 carried by a grooved spindle 55 which is enclosed by a concertina-like chamber 58. The shutter is pressed back by the rim of a tumbler and, when released, the chamber 58 expands and prevents drip by drawing any beer in the outlet back into the chamber.
